Contact lens with metal portion and polymer layer having indentations

Contact lenses having embedded polymer layers, and methods for forming the same are provided. In some aspects, the contact lens can include: a substrate; a metal portion coupled to the substrate; and a polymer layer attached to the substrate and the metal portion, wherein the polymer layer has one or more indentations. The metal portion can be associated with or a part of a power supply, antenna and/or circuit in various aspects. In some aspects, the substrate can encapsulate the metal portion and the polymer layer. In some aspects, a method can include: forming a metal ring; fabricating one or more components on the metal ring; forming a polymer layer ring having indentations; providing the metal ring and the polymer layer ring in a contact lens mold; and encapsulating the contact lens mold with conventional hydrogel, silicone hydrogel, silicone elastomer, polyacrylamide, siloxane-based hydrogel or fluorosiloxane-based hydrogel.
